Description

Technical Field

[0001] The utility model belongs to the technical field of drainage pipes, and specifically relates to a polyethylene composite steel frame concrete water supply and drainage pipe. Background Art

[0002] Highway drainage pipes can guide rainfall water flow and prevent water from accumulating on the road surface, thereby reducing the impact of water on the road structure and vehicle driving. The drainage pipe system collects rainwater from the road surface and surrounding areas, directs it to the drainage pipe, and finally discharges it to the designated drainage system, such as rivers or drainage channels.

[0003] The Chinese patent with application number CN202120634468.1 provides a concrete drain pipe, including a pipe body, and the two ends of the pipe body are respectively a notch end and a convex end; the pipe wall of the pipe body includes a concrete layer and a waterproof layer from the outside to the inside in sequence; it also includes an anti-corrosion ring that is sleeved on the pipe body and can move along the axial and circumferential directions of the pipe body; an internal thread section is arranged on the inner surface of the anti-corrosion ring; and external thread sections that match the internal thread section are arranged on both ends of the outer surface of the concrete layer. By arranging the anti-corrosion ring on the pipe body, when the two pipe bodies are connected by socket, the two pipe bodies can be fixed together by the anti-corrosion ring to prevent displacement between the two pipe bodies along their axial direction, thereby improving the firmness of the connection between the two concrete drain pipes, avoiding the situation where the two sections of the drainage pipe formed by connecting several concrete drain pipes are detached during long-term use, and ensuring the reliability of the drainage pipe during long-term use.

[0004] Conventional cement pipes are relatively backward, the inner wall of cement pipes is uneven and not smooth, impurities are easily deposited in the pipes, and polyethylene pipes are usually not strong enough. Therefore, a drainage pipe is needed that can prevent impurities from being easily deposited in the pipes and meet the strength and stability requirements. Utility Model Content

[0005] In view of the above shortcomings, the utility model provides a polyethylene composite steel frame concrete water supply and drainage pipe, which can prevent impurities from being easily precipitated in the pipe and prevent delamination; the utility model prevents the pipe from being crushed by cars when used on the side of the road; and the utility model improves the overall performance of the water supply and drainage pipe.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A polyethylene composite steel frame concrete water supply and drainage pipe comprises an inner polyethylene pipe, the outer periphery of the inner polyethylene pipe is sheathed with a steel frame cage, the outer periphery of the steel frame cage is sheathed with an outer polyethylene pipe; a plurality of protrusions are fixedly provided on the outer wall of the inner polyethylene pipe and the inner wall of the outer polyethylene pipe; a cement mortar layer is poured between the outer polyethylene pipe and the inner polyethylene pipe, and the steel frame cage is located inside the cement mortar layer.

[0008] Furthermore, an adhesive layer is attached to the outer wall of the inner polyethylene tube and the inner wall of the outer polyethylene tube.

[0009] Furthermore, the steel frame cage includes a plurality of steel bar rings that are coaxially and evenly arranged, a plurality of fixed steel bars are welded to the outer sides of the steel bar rings, and the cross-sectional diameter of the steel bar rings is larger than the cross-sectional diameter of the fixed steel bars.

[0010] Furthermore, the protrusions are distributed in a plum blossom shape on the outer wall of the inner polyethylene tube and the inner wall of the outer polyethylene tube.

[0011] Furthermore, the cross section of the protruding head is an I-shaped structure.

[0012] Furthermore, the protruding head includes a transverse rib, a side wall of the transverse rib is fixedly connected to the corresponding tube wall, and both ends of the transverse rib are fixedly connected to longitudinal ribs.

[0013] Furthermore, the side wall of the longitudinal rib is fixedly connected to one end of the transverse rib, one end of the longitudinal rib is fixedly connected to the corresponding tube wall, and the other end of the longitudinal rib is inclined outwardly relative to the transverse rib.

[0014] Furthermore, the wall thickness of the outer polyethylene tube is 7-15 mm, and the wall thickness of the inner polyethylene tube is 2 mm.

[0015] Furthermore, a polyethylene flared pipe joint is fixedly provided at one end of the outer polyethylene pipe.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) The utility model makes the inner wall of the water supply and drainage pipe smooth and flat through the structural design of the inner polyethylene pipe and the outer polyethylene pipe. Compared with the rough inner wall of the cement pipe, the utility model can prevent impurities from being easily deposited in the pipe. At the same time, a plurality of protrusions are fixedly provided on the outer wall of the inner polyethylene pipe and the inner wall of the outer polyethylene pipe, and the adhesive layer is used to make the cement mortar layer better bolted and integrated with the inner and outer polyethylene pipes, making it difficult to delaminate, while inheriting the strength advantage of the cement pipe.

[0018] (2) The utility model further improves the strength of the water supply and drainage pipes through the structural design of the steel cage, meeting the requirements of drainage pipes under the highway. At the same time, through the connection structure of the steel ring and the fixed steel bars, the thicker steel ring is conducive to bearing the vertical pressure, so that the pipes will not be crushed by cars when used beside the highway. The thinner fixed steel bars meet the fixing requirements while reducing the weight of the overall steel cage, saving costs.

[0019] (3) The utility model uses a plum blossom-shaped distribution structure to enable the protruding head to be better bolted to the cement mortar layer, thereby improving the overall stability of the drainage pipe. The protruding head design with an I-shaped structure and the transverse and longitudinal reinforcements further improve the connection stability between the inner and outer polyethylene pipes and the cement mortar layer.

Compared with the rough inner wall of the cement pipe, the utility model can prevent impurities from being easily deposited in the pipe. At the same time, a plurality of protrusions 500 are fixedly provided on the outer wall of the inner polyethylene tube 200 and the inner wall of the outer polyethylene tube 100. With the adhesive layer, the cement mortar layer 400 is better bolted and integrated with the inner and outer polyethylene pipes, making it difficult to delaminate, while inheriting the strength advantage of the cement pipe.

[0032] Furthermore, the steel cage 300 includes a plurality of coaxially and evenly arranged steel bar rings 310 , a plurality of fixing steel bars 320 are welded to the outer sides of the steel bar rings 310 , and a cross-sectional diameter of the steel bar rings 310 is greater than a cross-sectional diameter of the fixing steel bars 320 .

[0033] The utility model further improves the strength of the water supply and drainage pipes through the structural design of the steel frame cage 300 to meet the requirements of water supply and drainage pipes under roads. At the same time, through the connection structure of the steel ring 310 and the fixed steel bars 320, the thicker steel ring 310 is conducive to bearing the pressure in the vertical direction, so that the pipe will not be crushed by cars when used beside the road.

Through the design of the protruding head 500 with an I-shaped structure, the connection stability between the inner polyethylene tube 200 and the outer polyethylene tube 100 and the cement mortar layer 400 is further improved through the transverse reinforcement 510 and the longitudinal reinforcement 520.
